Foreign relative pose measurement technology

The UCARS-V2 system uses an adaptive radar guidance system to achieve autonomous landing. The system is directly developed from the AN/UPN-51 radar system. It can complete the autonomous landing and landing of the UAV all day long. The maximum detection distance is 4630 meters. The speed is 278 km/h, and the US Navy began to be installed in 2008.

France's DCNS's SADA autonomous deck take-off and landing system uses infrared sensors to accurately track drones. It can take off and land drones vertically on a moving flight deck in the case of Class 5 sea conditions. It takes less than 2 minutes to track. With an accuracy of 30 cm, it is much more accurate than a system that uses only GPS positioning. DCNS has used the system to successfully guide the S-100 UAV of the Austrian magazine to the French navy "Montecam" destroyer, which is not only complicated by day and night and bad weather conditions. The ability to take off and land can also be applied to most drone landings and is versatile. The SADA autonomous deck take-off and landing system mainly includes airborne optical beacons and shipborne infrared relative pose measurement equipment.

According to the Jane Group website reported in November 2012, the French Armaments Acquisition Agency and DCNS and the British Thales Company have completed the autonomous landing system of the ship-borne drone that does not depend on any satellite positioning system. The offshore test of the Fiat-class frigate, the D2AD autonomous take-off and landing system can provide the aircraft with a relative positional relationship with the landing platform at all times, ensuring the heading and attitude control of the aircraft, including on-board beacons and ships. The auxiliary equipment is composed, the airborne part is the indicator of the drone, and the shipborne auxiliary equipment uses the sensor on the flight deck to predict the hull motion.
